Mentioning every Twetch user (from 0 to 163607) would cost 818 USD. It might be a good marketing tactic if someone would have a valuable product or service that should get attention from the BSV community. But then posting a large message with so many mentions is probably not possible because of technical limitations, so it would be advisable to split the megamention message into smaller parts. (For example 100 mentions per message.)
